Hello.

I just experienced a very weird streaming problem with my TVIX HD M-6500A. I'm running it on NFS (using Allegro, on a Vista machine), to connect to a remote hard drive that is physically connected to my Vista machine. Everything worked seamlessly until yesterday night when I replaced my Netgear router by the Belkin N1 Vision (which has higher power and better signal for Wifi hence the change).
Now on the TVIX I can still access my shared drive and see all folders and files inside, but whenever I try to play one, the TVIX just freezes itself (stays forever on the screen Now Playing ....). After a long while (usually around 5 minutes) it comes back with an error saying that the file is not supported which is clearly wrong and I think indicates a connection problem.
Has anybody experienced such a weird problem before?

I'm getting crazy after one full night of fiddling with the router setup without success... (and I can confirm that any other computer connected to the router is working absolutely fine, be it wired or wireless).

I would really appreciate if somebody could try to help me out.

Many thanks

This could be very easy of very complex, is your TViX sitting in a Gigabit network? If so is your "DVD Server" NIC running Jumbo frames?

TViX's NIC has a limitation of 1500 MTU, anything higher and the machine will not work.

To check this yourself ping xxx.xxx.xxx.xxx -f -l XXXX

where the small xxx's are your TViX's IP address and the big XXX's are the MTU size, you will see that you should be able to only get a maximum of 1472 MTU size before the packet starts fragmenting. (28k is reserved for the ping info which you add to the max figure found).

If this is so..you need to limit the MTU size of your computer's NIC...

You're right the TVIX is sitting in a Gigabit network; it's a bit tricky: TVIX is connected to a bridge (netgear WNHDE111) which is connecting wirelessly to the access point itself connected to my Belkin Router. The Belkin default MTU is 1492, so that could be slightly over the limit. I'll test out tonight and will report.

Thank you

This may seem a little odd, but the NIC you need to concentrate on is the one "sending" the video...ie your PC...

I have a battery of NV+'s all on the Gig network but running at 1500MTU...

If your PC only connects to the outside world ('tinternet) and not to any other peripheral that makes use of a Gigabit network (very very few do), then the easiest thing you can do is limit the PC's NIC to 10/100.

Nothing wireless can touch a wired 10/100 NIC.

When I have to transfer files I reset the NASs to Gigabit, transfer, then drop them abck down to 10/100.

Hope that helps...

Hey AJSG

I've tried just that and found out that the max MTU size accepted by my network is 1468. Consequently I checked the settings of N1 Vision (interestingly in the Wired session) and the default is to use 1454 MTU. So I should be fine. Do you have any other suggestion ?

Thank you....

If it still doesn't stop the judder drop the MTU rate of your PC, or whatever storage device your TViX is reading the DVD transport from.

See my second message...

Sorry, I am not very familiar on how to do it exactly. My NAS is simply an external hard drive plugged via firewire on my PC. Could you please elaborate on how I can control the MTU there?

Also, by 'judder' do you mean my issue ?: the problem I'm having is even worse because the TVIX stays stuck when I try to start the remote video (or even remote mp3, same problem)

OK I've made some search and found out I need to set this up at the internet card of my computer (in device manager).

Looks like I'm getting somewhere ... at least in terms of understanding, and thank you very much for pointing me in that direction.

I'll give it another try this evening and will report.

Thanks again

You are getting there...set your PC's card simply to 10/100 and that should automatically disable Jumbo frames...then just check the MTU size...by defualt I think it is 1500...or 1472...note Ping header is 28k...so if 1472 is your fragmentation limit then you can happily set it to 1500.

All the best...

I just tried that since our Server has two Gigabit Network Interface Cards. Leaving one "as is" and setting the other to whatever value you can imagine (including 10/100) does not change the slightest bit. BD-iso does not run without stuttering, the same BD plays perfect from BD file structure. As far as one can tell this is caused by TViX limitations, at least this is what I learned from mpcclub.com

Ok, good to know, my 6500 hasn't arrived yet. However my PCH A-110 which has the same Sigma chipset runs perfectly *.m2tk files ripped by DVDFabExpress Beta. The 4100 which has an older chip will not decode the High Def stream fast enough and it judders.

The issue with the MTU size is a general limitation of any streamer and you would be surprised at how many problems it solves.

I suggest that you might still have problems with streaming if your server is running jumbo frames.

AJSG, unfortunately my problem still persists.

I have changed the MTU to 1454 (same as the one used by my router by the way) and I have confirmed that the TViX accepts up to 1468. So it should be fine... but same issue. I can access the shared drives directory and navigate no problem. But when I try to stream the TViX stays stuck forever on the loading screen (for any streaming: video and audio).

Any computer / mobile phone / other device connects very well to the network...

Do you have any other suggestion ?

I'm really getting desperate now ...

I was using a Netgear RangeMax before. Does anobody know what could possibly be the difference between the signal delivered by this one and the Belkin N1 Vision?

AJSG, unfortunately my problem still persists.

Ok, lets see...try and split the problem into the lowest number of complications.

Firstly lets take the Wifi out...so connect the TViX directly to the Switch.

If that doesn't work we need to look at the files themselves.

If you have any DVD handy download the trial version of DVD Fab Express and rip that DVD to your folder...then try and play the "folder" itself...the TViX should start playing on it own...

It doesn't work unfortunately (the TViX is already connected via wire to the N1). It was working using the RangeMAX (connected also via wire).

Ok so then your problem is one of two, the TViX is faulty or your file system is.

So...have you got a spare SATA HDD around the house? If so put it in the TViX and transfer one of your folders (the ones you currently use) to the TViX using the USB connection...

If not try ripping a DVD as I suggested and share a folder on your PC...NOT on an extrnal drive attached to your PC....

The TViX is working fine: I have quite a few folders on its internal hard drive and they all play without problems. (and since this network problem I have physically transferred all the files stored on the PC into the TViX itself, and they play great there).

So it is definitely an issue with the router, most likely actually with the way the router and the TViX communicate. There must be a funny setting somewhere in the router which makes the signal it sends non fully readable by TViX (although I can move through the remote file system without problem...), while when I was using the Netgear RangeMax it was all working fine.

Doubt it very much, now...you said you have a USB disk connected to the PC? That you are trying to stream from there to the TViX...have you tried using the standarsd TViX sharing software on a simple folder on your PC? NOT on the USB hard disk?

However it could be that certain streaming services on your router are interfering...have you tried turning off those various services?

Yes I have run stuff from the PC itself.

Now about the services: do you know which one i need to take down ?

Yes I have run stuff from the PC itself.

but you have the same problems? which started only with the change in router...

Now about the services: do you know which one i need to take down ?

Well, the easiest thing to do is to just disable all of them..I'm not familiar with that router so I don't know what it does...my Netgear Prosafe does very little except for dyndns...so its never been an issue for me....

AJSG, sorry to interrupt your troubleshooting bsauvage's problem. Just wanted to interject: and you consider physically moving drives to be a process for tinkerers? Sorry, but networks are for tinkerers, as this thread amply demonstrates.

At least he will have learnt something by the end....exercised 'ze litttle grey cellules...you will will have carried a little box from one room to another...many times over...

Yes, but I'll have accomplished what I wanted to do (watch my videos) without the unneeded and unwanted hassles he is going through. No tinkerering involved.

If you read his posts you see that his network was working fine, then he changed router...you still have to physically take whatever you want to watch from the inside of your PC to the WDTV, so your PC needs to be on...you need to transfer...if somebody comes round and wants to see something you have scurry away to the office....transfer a film (say that takes 15mins)...take all the way back to behind the telly...move things around etc etc etc...if that is what you like doing then fine...but its tinkering...

I can access everything I have ever ripped, fotorgaphed, filmed, recorded or downloaded within the boot time of the 6500....no tinkering....

Now, where you do have a point is that to get to this "set-up" it has taken me a lot of research...so that is why I try and be as loud as possible about the benefits of a NAS + Network + TViX setup...simply because it works...well.

Bwahahahahahahaha. You should go into comedy, you are so funny. Since I already store all my media files on portable drive, I don't need to have the PC on, I don't need to "sucrry to the office to transfer a film" etc. It's simple, I want to watch my media, I plug my portable HD into the WDTV and play. No messing around with routers, no troubleshooting network problems, no tinkering. All the messing around you do to get your network up and running, changing routers, etc *that* is tinkering. Plug and play isn't.


I can access everything I have ever ripped, fotorgaphed, filmed, recorded or downloaded within the boot time of the 6500....no tinkering....

I can do the same within the boot time of the WDTV.

And I'm glad it works well for you. the simplicty of the WDTV works well for other people, particularily those who have no need or desire to mess around with networking. Yes, that's right, not everone wants to or needs to have networking.

I can do the same within the boot time of the WDTV.

That's what backups are for (and as previously noted, if your media consits of CD, DVD and BR rips, the origional disks are your backup). Your RAID is fine, until it fails or gets zapped (yes, RAIDs fail too, and more frequently than you might think)....

OK gentlemen, back to the thread. AJSG I'm not familiar with the 'services; you are mentionning. And I'm wondering if this is something specific to the N1. I am not an expert here...

You've got to read the posts...its insane to rely on a single non monitored disk to keep all ones media. Read what information I have given you, if you do not see its use then simply ignore these posts. If on the other hand you would like some more information, please feel free to ask.

OK gentlemen, back to the thread. AJSG I'm not familiar with the 'services; you are mentionning. And I'm wondering if this is something specific to the N1. I am not an expert here...

I'm not familiar with what services the N1 provides either, you will have to read through the product's manual...or simply log into its web interface and have a little look around.

I find it very strange indeed that just by changing router the TViX is working so erratically. Are you able to borrow a router from somebody else?
